Viewing the Log from the Supervisor

You can view system messages from Device Manager if Device Manager is running from the same
workstation as the Fabric Manager Server. Choose Logs > Events > current to view the system
messages on Device Manager. The columns in the events table are sortable. In addition, you can use the
Find button to locate text within the table.
You can view switch-resident logs even if you have not set up your local syslog server or your local PC
is not in the switch's syslog server list. Because of memory constraints, these logs will wrap when they
reach a certain size. The switch syslog has two logs: an NVRAM log that holds a limited number of
critical and greater messages and a nonpersistent log that contains notice or greater severity messages.
Hardware messages are part of these logs.
Use the show logging CLI command to view the logs on the supervisor.

Viewing NVRAM logs

System messages that are priority 0, 1, or 2 are logged into NVRAM on the supervisor module. After a
switch reboots, you can display these syslog messages in NVRAM using the show logging nvram CLI
command. See
Example 1-2
